Day 7

Spaced Revision

Come back to Differentiation Of Trigonometric Functions after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • The derivative of $\sin x$ is $\cos x$
  • The derivative of $\cos x$ is $-\sin x$
  • The derivative of $\tan x$ is $\sec^2 x$
  • $\frac{d}{dx}(\sin x) = \cos x$
  • $\frac{d}{dx}(\cos x) = -\sin x$
  • $\frac{d}{dx}(\tan x) = \sec^2 x$
  • $\frac{d}{dx}(\sin^{-1} x) = \frac{1}{\sqrt{1 - x^2}}$
  • $\frac{d}{dx}(\cos^{-1} x) = \frac{-1}{\sqrt{1 - x^2}}$
  • $\frac{d}{dx}(\tan^{-1} x) = \frac{1}{1 + x^2}$

Common Mistakes to Avoid

The derivative of tan x is sec x, not sec² x.

The derivative of sin x is -cos x, just like cos x.

The derivative of sec x is sec x tan x, so derivative of cosec x must be cosec x cot x (without negative).

Memory Tips

Derivative of sin x is cos x

Derivative of cos x is -sin x

Derivative of tan x is sec²x

Derivative of sec x is sec x tan x
